Hey buddy, this is a great idea. I have had a go adapting it that you may be interesting in seeing where I saw some potential for jokes and repetition, and some character building of the wife.
Just came across this site today great resource for teaching.

Wife She and you?
Husband: With your money!
Wife: Right??? I???m not sure-
Husband: Even I couldn't believe it.
Wife: I???m not going to lie to you, I???m finding this particularly hard to believe.
Husband: Well just imagine what I???ve been thinking?
Wife: That???s part of the problem???
Husband: But then I realised! You know how there was that program the other night where, where??? they said that girls in their twenties are so much more interested in older guys than, like ever before right!
Wife: Oh right like ???men in their forties????
Husband: Yes men in their forties thank you very much! Well she must have seen it, and well, found that it er??? inspiring!
Wife: Good thing it wasn???t 20 year old serial killers then eh?
Husband: Yeah??? Good thing. Lucky escape for us all.
Wife: So. Tell me. After you had to suffer this??? attention from the maid, did you say anything? Put up a protest?
Husband: Well, without a moments hesitation, not one breath of should I-shouldn???t I ??? no, I slapped myself and said that she should stay away from me! Done and Done!
Wife: Oh that???s why your cheek is red! Aha!
Husband: Exactly!
Wife Why?
Husband: Why What?
Wife Why, exactly, would you, slap yourself?
Husband: Well, Well, I wanted to slap her, obviously, but then??? you know how much I respect women, so, to show her that I didn't like it, and I was suffering great pains in my heart, I slapped myself!
Wife: Right. Great pains.
Husband: I???m so glad to just be able to talk about it, you know? And not live with the great pains and longer.
Wife: Hmm??? I???m sure you???ll bounce back. You think she got the message? I mean shall I sack her?
Husband: Oh, that???s a bit harsh. No. She definitely understood how faithful I am to you, darling. All done.
Wife So, I should be grateful all???s back to normal.
Husband Grateful. You said it. Back to normal.
Wife Of course darling, once I???ve told her off about it.
Husband Now, let???s not be hasty, maybe she should leave. I mean it???s obvious she???s going be at it again and start moaning on about me, saying ??? I don???t know??? saying that I pinched her, for goodness sake, and, and I, proposed to run away with her, and taking your money???.
Wife and that she slapped you?
Husband Crazy I know!
Wife: What a pickle you???d be in???
Husband: It would be terrible wouldn???t it?
Wife Dreadful.
Pause
Wife So good that you told me first??? so I???d know the real story eh?
Husband: How could she think that I would leave you for her? I???m not that sort of man.
Wife Well I???m sure she???s now quite aware of the man you truly are. Now let???s see if we can balance out that red cheek.

About

Everyone experiences pain, of course. But a comedian has the ability to use their anger and intelligence to refocus and reconstruct their pain into entertainment. It's so obvious that it almost goes without saying, but comedians are generally more intelligent and sensitive than the average person. It's our undeniably superior (almost god-like) intelligence that made life difficult for us when we were children. We could see through the hypocracy and illogic of our parents and teachers, but because of our age and size we couldn't do anything about it. The more we pointed out the foolishness of our "superiors," the more they kept us down. But just as pressure and heat transform coal into diamonds, it's that frustration, social pressure and the heat of anger that transforms us into comedians.
